Feel the burn
"Definitely a thermogenic. Don't take before job interviews or when meeting your girlfriend's parents. Otherwise, great stuff."
BlackMarket Labs CUTS Diamond is the premium evolution of the AdreNolyn CUTS line — a fully transparent, fully dosed thermogenic pre-workout that combines eight thermogenic fat-burning ingredients with a complete pre-workout stack in a single 14.71g scoop. The name reflects the formula's design philosophy: time, heat, and pressure create diamonds, and CUTS Diamond applies that same principle to physique development — high-output training, thermogenic heat generation, and sustained pressure on the fat loss process simultaneously. Per serving: 2,500mg tri-carnitine complex (Tartrate + Acetyl + Fumarate), 30mg ProGBB™, 40mg CaloriBurn GP® Grains of Paradise, 50mg Evodiamine, 40mg Synephrine, 5,000mg L-Citrulline, 3,200mg Beta-Alanine, 300mg Caffeine Anhydrous, Alpha GPC, Choline Bitartrate, Mucuna Pruriens, and Rauwolscine. 25 servings per container. Natural colors and flavors. Zero sugar. Note: CaloriBurn GP® produces a mild spicy sensation — this is expected and confirms thermogenic activity. Not for tested athletes. Start with half scoop to assess tolerance. California Prop 65 Warning likely applies — confirm on label.†
Most thermogenic pre-workouts rely on caffeine and synephrine as their primary fat-burning mechanisms and call it done. CUTS Diamond stacks eight distinct thermogenic compounds with mechanistically different and genuinely complementary pathways. Understanding what each one does explains why the formula produces the intense, sustained thermogenic effect and visible sweating that users consistently report — and why it differs from standard pre-workouts with a token fat-burning ingredient or two.†
The three-form carnitine approach is the largest ingredient bloc in CUTS Diamond's thermogenic stack and the one with the most documented mechanism relevance to a training session. L-Carnitine's fundamental role is fatty acid transport into the mitochondria — it serves as the essential carrier molecule that moves long-chain fatty acids across the inner mitochondrial membrane, where they can enter beta-oxidation and be burned for energy. Without adequate carnitine, mobilized fatty acids cannot be oxidized regardless of how effectively other fat-burning compounds have stimulated lipolysis.†
L-Carnitine L-Tartrate at 1,500mg is the foundation — the most bioavailable and extensively researched carnitine form, with documented effects on post-exercise recovery, hormonal response to training (increased androgen receptor density in muscle), and fat oxidation during aerobic exercise. Acetyl-L-Carnitine at 500mg adds a brain-penetrating carnitine form that crosses the blood-brain barrier, contributing to the focus and mind-muscle connection quality of the training session while providing ALCAR's acetyl group for acetylcholine synthesis. L-Carnitine Fumarate at 500mg provides the Krebs cycle intermediate Fumaric Acid alongside carnitine — the fumarate acts as direct Krebs cycle substrate, supporting the aerobic energy pathway's capacity to oxidize the fatty acids that carnitine is transporting. Total carnitine complex: 2,500mg across three mechanistically complementary forms.†
ProGBB is the most unusual thermogenic ingredient in CUTS Diamond's formula and the one most responsible for the intense sweating that defines the CUTS Diamond training experience. GBB (Gamma-Butyrobetaine) is the immediate biosynthetic precursor to L-Carnitine in the body's natural carnitine production pathway — it is the compound that the enzyme gamma-butyrobetaine hydroxylase (with Vitamin C as cofactor) converts to L-Carnitine. Supplementing GBB at the ester (ethyl ester) form for improved bioavailability provides the body with additional carnitine precursor beyond what dietary intake provides, supporting endogenous carnitine synthesis.†
GBB's thermogenic mechanism is its most distinctive feature: it activates thermoreceptors and increases body temperature through a mechanism involving TRPV (transient receptor potential vanilloid) channel stimulation, producing intense, visible sweating during training within 15-30 minutes of ingestion. The sweating response from ProGBB is not simply a cosmetic effect — it reflects genuine elevation of core body temperature and metabolic rate, confirming that thermogenic processes are active. This thermogenic heat generation increases caloric expenditure above what the exercise itself produces. Users encountering ProGBB for the first time are often surprised by how intensely they sweat during a ProGBB-containing session versus their baseline — 30mg is an effective dose for a pronounced response.†
CaloriBurn GP® is NNB Nutrition's premium Grains of Paradise extract, standardized for the active thermogenic compounds in Aframomum melegueta (a West African spice in the ginger family). The mild spicy sensation that BlackMarket explicitly notes on the CUTS Diamond label comes from CaloriBurn — it is an expected and accurate indicator of the extract's bioactivity, not a formulation error.†
Grains of Paradise is one of the few sports nutrition ingredients with direct human clinical evidence for its mechanism of action. A 2014 study published in the Journal of Nutritional Science and Vitaminology (Sugita et al.) compared Grains of Paradise extract supplementation versus placebo and found that subjects receiving the active compound showed significantly greater whole-body energy expenditure and reduced visceral fat accumulation over the study period. The mechanism: Grains of Paradise activates brown adipose tissue (BAT) through beta-3 adrenergic receptor stimulation. Brown fat is thermogenically active tissue (unlike white adipose tissue, which stores fat) that burns calories to generate heat through a process called non-shivering thermogenesis. BAT activation increases the rate at which the body burns calories through mitochondrial uncoupling — ATP synthesis efficiency is reduced in favor of heat production, increasing total caloric expenditure. At 40mg, CaloriBurn is at the dose range used in published research.†
Evodiamine is a quinazolinocarboline alkaloid extracted from Evodia rutaecarpa — a fruit used in Traditional Chinese Medicine. Its thermogenic mechanism involves activation of TRPV1 (transient receptor potential vanilloid type 1) receptors — the same receptor activated by capsaicin (the active compound in chili peppers) — which increases sympathetic nervous system activity, elevates body temperature, and promotes heat-generating thermogenesis. Evodiamine at 50mg is a meaningful dose for thermogenic effect, contributing to CUTS Diamond's overall heat generation and caloric expenditure alongside CaloriBurn and ProGBB. Evodiamine also demonstrates demonstrated effects on catecholamine release (dopamine and norepinephrine), contributing to the mood and motivation component of the training experience.†
Synephrine (p-Synephrine, from Bitter Orange / Citrus aurantium) is a beta-adrenergic agonist that primarily activates beta-3 adrenergic receptors in adipose tissue — the same receptor population that CaloriBurn's Grains of Paradise activates — increasing lipolysis (the breakdown and release of stored triglycerides from fat cells into the bloodstream). At 40mg, Synephrine is at the upper end of sports nutrition dosing and produces meaningful beta-adrenergic stimulation for fat mobilization, appetite suppression, and metabolic rate increase. Synephrine is prohibited by WADA and NCAA. Not for tested athletes.†
Rauwolscine (from Rauwolfia Vomitoria root) is the alpha-2 stereoisomer of Yohimbine, with approximately 4-8x the binding affinity for alpha-2 adrenergic receptors versus standard Yohimbine. Alpha-2 adrenergic receptors in fat cells are the primary physiological brake on lipolysis — when occupied by their endogenous ligands (norepinephrine, epinephrine), these receptors suppress the release of fatty acids from fat cells, especially in the stubborn subcutaneous fat depots of the abdomen, hips, and thighs where alpha-2 receptor density is highest. Rauwolscine's alpha-2 blockade removes this inhibition, allowing the beta-adrenergic fat mobilization signals from Synephrine, Evodiamine, and CaloriBurn to operate without counter-regulatory suppression. Rauwolscine also acts as an MAO inhibitor at higher doses and produces meaningful CNS stimulant effects at the doses used in supplements. Rauwolscine is prohibited by WADA and NCAA. Not for tested athletes.†
CUTS Diamond is not a fat burner with token pre-workout ingredients added for marketing. The pre-workout half of the formula is fully dosed and stands on its own merits — making it a legitimate choice for maximizing the training session that the thermogenic stack is enhancing.†
L-Citrulline at 5,000mg (pure L-Citrulline, not Citrulline Malate) delivers approximately 5,000mg of actual Citrulline — equivalent to roughly 7,500mg of standard Citrulline Malate 2:1 in actual Citrulline content. This is a full clinical pump dose that drives meaningful nitric oxide production, vasodilation, and the enhanced blood flow that improves both pump aesthetics and nutrient delivery during a cutting session. Beta-Alanine at 3,200mg is the established clinical dose for Carnosine buffering and fatigue delay. Caffeine Anhydrous at 300mg provides strong, reliable energy and focus without the dual-source complexity of some higher-stim products. Mucuna Pruriens (L-DOPA source) contributes dopaminergic motivation and mood. Choline Bitartrate and Alpha GPC together provide the dual choline stack for acetylcholine support and mind-muscle connection — the same approach used in Super bioFREAK WTF at similar intent. Betaine Anhydrous supports power output and body composition over time.†
The original AdreNolyn CUTS is a proprietary blend formula — individual ingredient doses are not disclosed. CUTS Diamond is fully transparent — every dose is listed on the label. This matters beyond marketing: when you know you're getting 1,500mg LCLT, 40mg CaloriBurn at a research-validated dose, and 30mg ProGBB, you can make informed decisions about stacking and cycling rather than guessing at what's actually in your serving. CUTS Diamond is also 25 servings versus the original's 30, at $5 more — the cost-per-serving difference is real but reflects the significantly more comprehensive and precisely dosed formula.†
Mix 1 scoop in 8-10oz of water 15-30 minutes before training. Start with half a scoop to assess individual tolerance — the Rauwolscine (Alpha Yohimbine) in particular can produce anxiety or discomfort in sensitive individuals at full dose. Do not exceed 1 scoop per day. Do not combine with other stimulant-containing products. Do not take within 6 hours of bedtime. Expect pronounced sweating — this is expected and reflects the ProGBB and CaloriBurn thermogenic activity. Not for persons under 18. Not for pregnant or nursing women. Not for tested athletes.†
